To all whom "it may concern: I

Be it-l nown that we,'JosEP`H F. LETELLIER and AnoLPH LEITELT, ot' Grand Rapids, in tho county of Kent, and State ot' liiichigan, have invented a, new and useful Improvement in Machines t'or Edging, and Splitting.: Lumber; and we do hereby declare that thel following,r is a full, clear, and exact description ot' thc same, reterence being had to the annexed drawings, mak-ing part ot this speeiticatiou, in which- Figure 1 is-a plan or top'view ot' the machine, showing the upper tcedrollers,.the shaltv andpnlley t'or driving the same, thc saw-mainlrcl, andthc saws, together with the index-wheel tbr h'xng the positions of the saws; l

AFigure .2 is a front elevation, showin,"r the feed-roll-KV ers, the gearing; which drives them, and the lever for raising the upper one, together with the shalt and con- Figure 3 is an end elevation of ing the parts in position;

Figure. 4 is a plan or top View ot' a portion of the frame ot the machine, showing the. sa'w-imindrel, with the machine, showhe mandrel; and 1 Figure k5 is a section on line :l: a: o'f iig. 4.

Corresponding letters referto corresponding parts in the several tigures.

This invention relates to that class of machines which are used fbredgiug and splittingr lumber; and

It consists in providing such machines with an in? ting any desired width ot' strip within the capacity of the machine, trom the board or plank; and lhe invention further consists-in the combination and arrangenient'ot the parts composing the machine. A A, in the drawings, reln'esent a trame-work of timbers, upon which the machine maybe placed, they hay-ing a standard, A3, erected thereon to receive and hold the outer end ot' the shaft to which thc index wheel is-secured. This ti'axne and its standard are not necessary parts of the machine, and may 4be dispensed with, if desired, by attachingl to the frame a hanger to support the shaft alluded to.

A represents thc framework of the machine, which may be made of cast-iron or ot' wood, and it isto have the requisite bearings attached to it, or formed in it for the shai'ts and rollers which extend across it.

B represents a shaft, which has its bearings in boxesattached to the rear upper surfaces o't'the frames A* A'. To' one ot`t.he.;0ute1 ends of this shaft a pulley, B, is attached, over which a belt passes for driving the feed4rollers.

Upon this shaft, just inside of the. drivingpnlley,v` thereis a small gear-wheel, Bi', secured, which meshes.

into and drives a larger wheel, B, which is to he secured to the outer end ot' the lower feed-roller B5.

VB* B5 represent the rollerswhich feed thclumberto the saws, they beint.;- arranged iu the rear ot' such saws, so that as soon as thc ends ot' the plank, or the strips cut therelrom, reach this roller, they will pass between the saine, and be by them carried tbrward.

These rollers have theirbearings in boxes, which work in standards B6, secured to the upper surface of the i'rame A A, as shown in tig. 3, lhe lower'one of these rollers` extends beyond the box, in which it ro-l tates for a distance sntticient to enable it to receive the wheel B, by which it is driven.

Greprescnts a shaft or mandrel, which also has its t bearings in boxes secured to the frames A A, while upon oneI ot' itsouter ends it carries atlriving pulley, C, oven-,which the belt passes which drives the saws.

Outside ot' each ofthe boxes in which this shat'trevolves it carries an adjustable collar, G2, which are. for the. purpose ot'preventingan y end traverse ot'such shaft.

C aml C* represent two circular saws, which are attnt-hed to asleeve, C, which slides upon but rotates with the shaft C.v li/lidway between these saws thc sliding sleeve is provided with a groove, intoV which thc bit'urcated end ot` an arm enters, for the purpose otslidi'tg the same upon the sei-ted in suelrshatt to cause suoli sleevcto rotate therewith, but permit its longitudinal movement thereon. The red lines in fig. 1 show that these two saws may be moved upon the shalt, which movement .may extend tln'oughout that portion which is between the fixed saw C and the journal upon the opposite end of the shaft. These saws may be set at any ldesir'e'd distance apart, so as to cut any fixed width of strip.

(l5-represents a saw, which is to be tixed uponthe shaft by means ot' suitable collars attached thereto,

and so that will edge the board in straight.

D represents a shaft or rod, which extends across the trame, and has its bearings in projections formed upon the legs of the frame.

Upon each outer end of this shaft there is to be attached an arm, D1,'t.o the outer end of which acrankpin is to be secured, and upon which works thc connecting-rod or yoke D2, which has a slot formed in itl at the point where it passes the journal ot'- the lower lfeed-roller, while upon the upper ends ot' these rods or yokes there is to be an aperture, which will fit upon theouter ends ofthe journals oi-` the upperiteed-roller,

while just above such apertures there is t0`be formed shatt, a feather being inany required width ot stripmay be cnt;` betweenl it and the movable saw, while the fixed saw v cases where it is not already an eye t'or the reception of a connecting-rod or link,

which extends therefrom up4 to and connects with theY short arm ot' level' D4, by which the upper feed-roller is raised or lowered at pleasure, the slots in D2 allowing it to move up and downwitbout in the least at'- fecting the lower roller.

E represents a rod. which passes through the two sides ofthe frame A A, to which it is secured by nuts upon-itsv outer ends, and upon which slides-the socket E2, which hasnpon its under side a projection, iu` which au aperture is formed which forms a right angle to itsuppcrportion, so that it may traverse along-the rod F, funn side to sident' the machine, and 'at the same time support the shaftE", which is secured to or within the socket, having its outer bearing in the standard A ot'th'e frame, and upon its outer end the index-wheel Et, which is serrated u'pou its periphery,

or has prqiegting points formed thereon, which may belnarkedl to correspond with the number ot' inches that the saw C* will be from `saw C5 when any one ot' such parts is brought opposite a tixed point upon the standard A, and thus'the width ofthe strip to be; cut will be determined by turning such wheel.

Upon that portiiriot' shaft E which is outside of the soket E, in which it rotates, there is to be secured z|.-geal'\\'lleel, El, which. is keyed or otherwise attached to theshai't, so as rotate wtlrit, and so ar- -rangetl as to mesh into the teeth of a rack for moving A'the saws.

F represents the rod above alluded to, which is lo- 'ca-t-ed above the rod E, having itseuds secured in the ends ot' G, soon to be described. socket E2 slides. F1 represents a rack, which isarranged. upon the slide F, so as to be directly above the wheel 1"', and so as to be moved transversely across the machine by Upon this rod Such wheel. i

F? represents an arm, one end of which is to be hifurcatelhso as 1.o embrace the sleeve C", upon the. shalt C, to which saws G and C5 are attached. The opposite end ot' this arm is to be secured toa sliding t'rame, F, which mores upon rod l", and to which the rack F1 is secured, the arrangement being such, that as the dial-wheel F4 is' turned, the saws will be moved upon thc shaft, as above described.

G represents a table, over which lche lumber to be Patent, is-

edged or split. passes on its wayto the saws, it being of the torm shown in figs. 1 and 5, and secured to the upper surl'ace otf the t'rame Al A1.

The upper surface ot' this table is to be corrugated, such eorrngations being in 4lines parallel with the move- Vments otl the. lumber to be cnt, so that asy the board orplank is placed upon this table, and pushed forward to and past the saws, the points or edges ot' such corrugatious shall t'orm guides for the hnnber,and prevent it tifom being turned out;- of aline with thensides of the saws;l

We are aware that a. patent was granted to J.

llayesaud Martin Newman, for au'edging-machine having two saws upony a mandrel, one of Vwhich is capable ot' being moved thereon by `meaus of a screw.

XVe. do not .claim the devices shown in the above referred to patent., neither do we claim any conibina- '.tiou or arrangement there shown; but

Having thus described our invention,

What we claim, and desire to` secure by Letters -1. In combination with a machine constructedsubstantially as herein described, a dialnvheel tbrdetermining Vthe position ofthe saw or sawsupontheir shaft, 'and the width of the strip to be cut from (the board or plank.

2. .'lhe combination and arrangement of the dialwheel l* with the gear-wheel El, rack 1",..sliding,r flame Ff-, and ar-xn F, tinmoving the saws upon the `shaft, substantially as and for the. purpose set t'ortb.

3. The within-described arrangement ot' ,the saws upon their mandrel, it being such thattwo strips may `be cutli'om a board or plank at one and the saine time, one of which will bc ot' a iixed -width and the other ot' any desired width, the. latter being dependent upon the position ot the movable saw with reference to the tixed saw.

In testimony whereof', we have signcdour names to this specification, in the presence ot' two subscribing witnesses.
